Shouldn't be hard, since it already filters some of them: (dolist (file (sort (file-name-all-completions "" dir) 'string<)) (unless (member file '("./" "../")) <<<<<<<<<<<<<<<<<<< Even better: compute completion-regexp-list so that IGNOREs are filtered by file-name-all-completions in the first place. Patches welcome.
